Title: Computers and Thin Shell Analysis

Author(s): David P. Billington

Publication: Symposium Paper

Volume: 16


Appears on pages(s): 77-95


Date: 1/1/1967

Thin shell analysis formulated by finite elements is described as a general procedure well suited to computers. Analysis of the individual elements can conveniently be done by numerical integration and examples are described for barrels, domes, and shell walls. Confidence in these analyses are established by studying for all shells the maximum integration length and for domes the required ficticious crown opening. The superposition method of analysis is described for continuous folded plates and finally a brief discussion is given of extensions in the numerical integration of barrels to include the inelastic behavior of reinforced concrete thin shells, particularly above working loads.
